The high school I attended no longer exists, which figures. It was the best one in the Whittier Unified School District. Sierra HS, Whittier, CA. Plastics was a course of it's own, and I took that waiting for a slot in the machine shop class, which I go my final semester, just before graduating in June of 1973. Use the SB lathe and shaper to make a tap wrench, and a small riveting hammer. Gave those to my Grandpa, and then got them back after he passed on in 1977. I think they may still be here someplace. I have two sheds full of boxes that haven't gotten much disturbed in the past 25 years. Spent 38 years looking for a lathe I could afford before I found one. I was in Germany twice, drooling over an Emco Maximat 5, I think it was. Some of the German department stores had lathes for sale. Couldn't get enough cash to buy one the first time, in 1984, when I was up there for a surgery they couldn't handle in Turkey, and the second time I was there was in 1991-1996, when the exchange rate between the Mark and Dollar flipped, and I couldn't afford it again. In 2008 we got a Harbor Freight in OKC, and I got my HF 93212 mini-lathe for, I think, $369, with tax and the 20% discount coupon. Might have been $269. Anyway, and despite the internet, I'd forgotten EVERYTHING I'd learned in the class, and had to start all over again. I also wasn't getting enough practice, so it was essentially time wasted until I started the new class in early 2015. I completed a couple of their projects in one try. And a few took as many as ten attempts to get right enough to pass the 85% standard. I can't see anyone hiring me as a machinist unless they're absolutely desperate. Like post-apocalypse desperate. ;)
I have successfully been several kinds of mechanic and electronics tech, and I enjoy that kind of work, but I wanted to branch out a bit. So now I'm leafing, and going to see if I can figure out a way around my little shop catastrophe. My lathe stand I cobbled together isn't going to work as is.

Way back in 1967 the Grade 8 Shop class taught printing, pottery, wood working, plastic vacuum forming and metal working. As part of the general all around education for boys (girls were not allowed to take that class).
The metal working project used a drill press for drilling holes, hack saw for cutting 1/4" steel rod, tap and die for making 1/4-20 holes, a lathe for making a handle from aluminium and a shaper for cutting teeth on a block. All to make a meat tenderizing hammer.
Still have it. See attached photo. Still use it. I guess that makes it 54 years old now?
My next foray into real metal working was the purchase of a Unimat DB-200 in the early 80's after a gas welding course in the mid 70's. I tried to make a robot arm with that lathe/mill. Big failure. Didn't really know what I was doing. After that it wasn't until the mid 90's that I discovered the Gingery Series of books in the Library. I was hooked. There really isn't anything better than making your own slip roll, power hacksaw etc to create a furnace to create a lathe. Follow the direction exactly (also an important critical skill) and the metal working education improves.
The Gingery gets very little use now that I have the Heavy 10L.
I'll also be the first to say I'm still an incompetent machinist. I wouldn't hire me. My mistakes outweigh the successes.

Despite have spent the past 6+ years and still not having completed what was supposed to be a precision manual machining class, I am not, and probably never will be, a professional machinist. Even though that is the point of the class I'm taking. But I've spent a fair portion of the past 48 years reading everything I could lay my hands on (and collecting as much as I could) on machining, and making things. Fair bit of practice in making, too, but very little of it involved machine tools until about 13 years ago. Since storage capacities and display capabilities have increased markedly in the past dozen or so years, also, I'm developing a backlog of stuff I have collected but not yet read. And frankly, I've not been focused enough to get good at much of anything, but one thing I'm seeing in my class, which is really a feeder for the CNC Machining course, is that many things that were standard practice in machine shops are dropping out of the processes these days. My school does not teach anything about turning between centers, for example. They don't have any faceplates in the class area. They do mention centers, but don't actually have any. They have one lathe set up with a taper attachment, and one more with a collet closer. I've learned enough that I could probably get an entry-level job as a manual machinist in a manual shop, once I complete the little bit of the class I have left to do. Maybe. If there are any such jobs any more.

I agree that sometimes we tend to forget that we can build a solution rather than buy. As an example,
With the end result being able to use the mill to solidly hold a tap and power tap.
Scary to watch but really cool.
And yes, sometimes the best way to hold something on the lathe is with a good solid faceplate.
I can't do everything he listed yet, either. And since I'm already 66 years old, I may not make it ever. It is inspiration and aspiration. Among other things, he felt that folks like me who can't handle higher maths are "at best, tolerable subhumans." So I'll be as tolerable as I can manage, and not worry about it otherwise. ;)

I love your attitude and your knowledge. I have a small mill, besides my SB 9C. Recently, with a project in the mill, I realized I had done things out of order: there was a small part I should have made first. Out came the Palmgren milling attachment for the 9C. BTW: I have the SB milling attachment, too. While it's a good, solid piece, the Palmgren is far more versatile.
It IS an addiction. While I can only dream of shoe-horning a larger additional lathe into my single garage bay shop, I do have two mills, although one of them is in pieces, not yet having been assembled since trucking it here from far, far away. BUT, I'm on the move. Between now and Christmas, I've promised myself. The thing I'm looking forward to is a feature it will add to the shop: horizontal milling.
Love Heinlein, too. Can't do everything he listed, but I'm working on it.

The original builders of machines used hammers, chisels, files, hacksaws, and scrapers to make the machines that built the industrial age. In more modern times, folks have built t-slotted tables with similar tooling, flat stock, and bolts or rivets to make similar tables. Admittedly, such tools are slower. I made the T-nut for my QCTP on my Atlas lathe with a hacksaw and files. You can do anything you want if you recognize the possibilities of your workshop.

Many thanks for your comments. I thought that their might be someone out there who had managed to fit a myford slide to a SB. Regarding the Pine Groves cross slide kit that has been mentioned. It is only a kit consisting of a casting and a drawing with machining instructions. You need access to a milling machine to machine the T slots etc which I have not got!! If I had a milling machine why would I want a milling table on the lathe.
